Problem: When signing in I get an error message that I am using illegal characters or that I should only use alpha numeric characters. What should I do.
Likely Reason: That message means that you may have inadvertently entered a space-bar character or any of the following characters which are unacceptable for sign in:
!@#$%^&*()_+-={}[]\?/"'<,>.:;
Recommendation:
Use only a-z and 0-9
